@ -5,10 +5,12 @@ Properties:
- " st,stm32mp157-syscfg " - for stm32mp157 based SoCs,
second value must be always "syscon".
- reg : offset and length of the register set.
- clocks: phandle to the syscfg clock
Example:
syscfg: syscon@50020000 {
compatible = "st,stm32mp157-syscfg", "syscon";
reg = <0x50020000 0x400>;
clocks = <&rcc SYSCFG>;
};
